Margaret Mead.

Margaret Mead (December 16, 1901, Philadelphia – November 15, 1978, New York City) was an American cultural anthropologist, she was both a popularizer of the insights of anthropology into modern American and Western culture, and also a respected, if controversial, academic anthropologist. Her reports about the purportedly healthy attitude towards sex in South Pacific and Southeast Asian traditional cultures amply informed the 1960s sexual revolution. Mead was a champion of broadened sexual mores within a context of traditional western religious life. A committed Anglican Christian, she took a considerable part in the drafting of the 1979 American Episcopal Book of Common Prayer.
